The Justice Department has sent a sweeping request to every Roman Catholic diocese in the United States not to destroy documents related to the handling of child sexual abuse, a sign that the federal investigation into the church could grow far more extensive.
Catholic bishops have been asked by the federal government to retain their files on a broad array of internal matters, including sexual abuse investigations, and the transfer of priests across state or international borders, or to treatment centers. The request includes documents contained in "secret archives" -- the confidential files that are kept by each diocese.
